Abstract In this study, we fabricated a porous polymer membrane using Mg(NO3)2 as the additive with water-pressure. The pores in the membrane were fabricated uniformly using Mg(NO3)2·6H2O and water pressure treatment. Pore size could also be easily controlled by adjusting the water pressure. The generated pores in CA polymers were confirmed by scanning electron microscopy (SEM) images. The coordinate interactions between CA polymer and Mg salts, and ionic states of Mg(NO3)2 were investigated by FT-IR and Raman spectroscopy, respectively. Thus, we succeeded in fabricating porous materials by employing a low-cost, environment-friendly, and simple method with both Mg(NO3)2 and water-pressure.

通过水压处理控制含镁盐醋酸纤维素中的孔隙，用于分离器

摘要 在本研究中，我们以Mg(NO3)2 作为添加剂，在水压下制备了多孔聚合物膜。使用Mg(NO3)2·6H2O和水压处理均匀地制造膜中的孔。孔径也可以通过调节水压轻松控制。通过扫描电子显微镜 (SEM) 图像证实了 CA 聚合物中产生的孔。CA 聚合物和镁盐之间的配位相互作用以及 Mg(NO3)2 的离子状态分别通过 FT-IR 和拉曼光谱进行了研究。因此，我们通过采用低成本、环保且简单的 Mg(NO3)2 和水压方法成功地制造了多孔材料。
